SYSTEM AND METHOD FOR MONITORING OPERATION OF A PRESS ASSEMBLY
First Claim
1. A method for monitoring operation of a press assembly including a press having a replaceable die attached thereto, the die being configured to form a workpiece, the press including a plurality of press elements, including a movable portion for moving a portion of the die, a mechanical power source, and a plurality of power transmission elements for transmitting mechanical power from the mechanical power source to the movable portion of the press, the method including:
- establishing a baseline vibration level for a first location on the press assembly, the baseline vibration level defining a boundary for vibrations beyond which one or more of the press elements have a reduced life expectancy;
measuring vibrations at the first location on the press assembly during operation of the press;
measuring vibrations at a second location on the press assembly during operation of the press; and
correlating the measured vibrations at the first location with the measured vibrations at the second location to establish a relationship between the vibrations at the first and second locations.

Abstract
A system and method for monitoring operation of a press assembly includes establishing a baseline vibration level for a first location on the press assembly. The baseline vibration level defines a boundary for vibrations beyond which one or more press elements have a reduced life expectancy. Vibrations are measured at the first location and also at a second location during operation of the press. The vibrations measured at the first location are correlated with the vibrations measured at the second location, and a relationship between the vibrations at the first and second locations is established. Vibrations measured at the second location can then be adjusted and compared to the baseline vibration level to determine if adjustments to the press operation need to be made, or if certain press elements will need to be replaced prior to their expected life span.

12. A method for monitoring operation of a press assembly including a press having a replaceable die attached thereto, the die being configured to form a workpiece, the press including a plurality of press elements, including a movable portion for moving a portion of the die, a mechanical power source, and a plurality of power transmission elements for transmitting mechanical power from the mechanical power source to the movable portion of the press, the method including:
-
establishing a baseline vibration level at a predetermined location on the die, the baseline vibration level defining a boundary for vibrations beyond which one or more of the press elements have a reduced life expectancy; measuring vibrations at the predetermined location on the die during operation of the press; measuring vibrations at a plurality of predetermined locations on the press during operation of the press; and correlating the measured vibrations at the predetermined location on the die with the measured vibrations at each of the respective predetermined locations on the press to establish respective relationships between the vibrations at the predetermined location on the die and each of the predetermined locations on the press. - View Dependent Claims (13, 14, 15, 16)

17. A system for monitoring operation of a press assembly including a press having a replaceable die attached thereto, the die being configured to form a workpiece, the press including a plurality of press elements, including a movable portion for moving a portion of the die, a mechanical power source, and a plurality of power transmission elements for transmitting mechanical power from the mechanical power source to the movable portion of the press, the system comprising:
-
a sensor for sensing vibrations at a location on the press; and a control system in communication with the sensor and including at least one controller, the control system being configured with; information establishing a relationship between the vibrations measured at the sensor location and vibration data measured at a predetermined location on the die, and a baseline vibration level defining a boundary for vibrations beyond which one or more of the press elements have a reduced life expectancy, the baseline vibration level being established based on vibrations measured at the predetermined location on the die, the control system being further configured to define a fault condition when a vibration measured by the sensor correlates to a vibration at the predetermined location on the die that exceeds the baseline vibration level. - View Dependent Claims (18, 19)
